Expanding on my comment on the ticket, I’m really quite happy with using codahale/dropwizard metrics with Solr. I don’t know if I’m comfortable just sharing a screenshot of the resulting grafana dashboard, but I’ve got, per-host:
- Percentile latencies and rates for GET vs POST (which in solrcloud generally maps to top-level-query vs shard-request & update) (From the jetty-metrics plugin) - Log rates by log level (from the logging-metrics plugin) - GC time (from the jvm-metrics plugin) - Thread counts (same) - Percentile latencies and rates per query “performance class” (from my metrics-aware backup request handler - https://github.com/whitepages/SOLR-4449) - Backup request rates (same) I’ve been agitating the idea of getting metrics more tightly integrated for at least a year, maybe longer. I’ve been using the jetty metrics plugin since at least Solr 4.9, and have upgraded and re-added it at least twice. On 11/1/16, 11:56 AM, "Walter Underwood" <wun...@wunderwood.org> wrote: Anybody? It seems like this would be a solution for SOLR-4735, which has been open for 3.5 years. https://issues.apache.org/jira/browse/SOLR-4735 <https://issues.apache.org/jira/browse/SOLR-4735> wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Oct 26, 2016, at 12:02 PM, Walter Underwood <wun...@wunderwood.org> wrote: > > Anybody using the CodaHale metrics.jetty9.InstrumentedHandler?
